To illustrate, think of your metabolism as a campfire. If you only feed the fire a few twigs, the flame dies out.
On the other hand, when you replenish the fire with the right amount of wood, the flame burns at a steady rate.
In the same way, it’s important to eat enough calories to fuel your metabolism. Because a steady metabolism is a key to sustained weight loss.
That’s why my weight loss calculates your BMR (base metabolic rate). And gives you a minimum number of calories to eat.
